ingest

'suck it up' is the definition.
I can't judge whether this definition defines the answer.

'for laughs on the radio' is the wordplay.
'for laughs' becomes 'injest' (I've seen this in another clue).
'on the radio' indicates a 'sounds like' (homophone) clue.
'injest' sounds like 'INGEST'.

Can you help me to learn more?

(Other definitions for ingest that I've seen before include "Consume food" , "Take nourishment into the body" , "Swallow -signet (anag)" , "Take in with tinges" , "Swallow, absorb" .)
